Precautions
■ Correct Use
Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON continuously
for long periods (without switching) can lead to unstable contacts
because the heat generated by the coil itself will affect the insulation,
causing a film to develop on the contact surfaces. Be sure to use a
fail-safe circuit design that provides protection against contact failure
or coil burnout.
Seal integrity during cleaning will last 1 minute at 70°C. Complete
cleaning within these conditions.

Relay Handling
When washing the product after soldering the Relay to a PCB, use a
water-based solvent or alcohol-based solvent, and keep the solvent
temperature to less than 40°C. Do not put the Relay in a cold
cleaning bath immediately after soldering.
When the lines must curve, an elbow can be used as shown
in the diagram. A distance (D) between the lines of approxi-
mately twice the line width is sufficient.
with a thickness of 1.6 mm, the above graph will yield a w/h ratio of
1.7 for a dielectric constant of 4.8. Since the base thickness is
1.6 mm, the width will be h × 1.7 ≈ 2.7 mm.
The thickness of the copper foil “t” is ignored in this design method,
but it must be considered because large errors will occur in extreme
cases such as a foil thickness of t ≈ w.
Furthermore, with the Micro Strip Line design, the lines are too
short for the G6Y’s intended frequency bandwidths, so we can
ignore conductive losses and the line’s attenuation constant.
